It turns out what while aviation’s contribution to global emissions has been growing as worldwide air travel has grown (pre-pandemic), it hasn’t increased in relative importance. Between 2000 and 2018 aviation has steadily accounted for about 3.5% of climate-affecting emissions, and that includes commercial and cargo flights, according to a new study from climate scientist David Lee and Manchester Metropolitan University.
What’s especially interesting though is just how aviation appears to affect climate. It’s contrails that matter most – water vapor and exhaust forming ice crystals.
